My mini-excavator has an issue that's been driving me nuts. The 'bleed screw' is frozen in the cylinder, and stripped. I would like to fix in place. Have hit it a few times with PB blaster, but no success. stripped when I bought it. Afraid to try heat (open flame) as there is just too much grease/oil around (unlike the 'new' pic clipped from repair manual)
This is basically a sealed hydraulic cylinder, that you pump up with a grease gun to put pressure on the tracks. Access is very limited through that cover plate.
#2 & #9 below.
I suspect I'll remove the whole cylinder if we get a warm day, and weld on a nut.....?
